I have a large amount of copper sulfate available and I am interested in obtaining copper chloride from it. What is the easiest way to do so?
I have considered mixing an aqueous solution of copper sulfate with sodium chloride, but I think that it would be difficult to separate the resulting sodium sulfate from the copper chloride. My other idea is to first react the copper sulfate with sodium carbonate and then react the resulting copper carbonate with hydrochloric acid, which would produce copper chloride (the other products would be $\ce{CO2}$ gas and water). I am trying to find a cost effective method for performing this reaction.
